San Francisco Mayor Gavin Newsomhas become used to uninvited guests showing up in unexpected places. They're members of Service Employees International Union Local 1021, and they're hopping mad over 500 layoffs this month of clerical workers and certified nursing assistants.

Their loud chants forced a Monday evening reception for the new police chief from the mayor's balcony into his office. They've disrupted two previous City Hall receptions, staged die-ins in front of his SUV and, according to Newsom, threw ketchup on his wife at June's Pride Parade. And they're just getting going.

Robert Haaland, an organizer for the union, said the gubernatorial candidate should get used to it. "We plan on dogging him on the campaign trail," he said.

Even the Monday appearance in L.A. with former President Bill Clinton? "That's the plan," Haaland said.

The union says the mayor reneged on a promise to place a revenue measure on the November ballot in hopes of staving off layoffs. The promise came in exchange for SEIU contract concessions agreed to in June that saved the city $38 million. The union adds that the vast majority of layoffs affect minority women.

The mayor's office counters that he never guaranteed he would not lay off people during an economic recession - and that the union rejected some of his cost-saving ideas, like contracting out jail health workers.

The mayor was reportedly steaming mad in his meeting Tuesday morning with department heads and said that he'd had "enough of their lies" and that negotiations with SEIU had broken down.

"They're unfortunately misleading people and not telling the truth," he told us later in the day, adding that the layoffs were planned as part of the budget negotiated with the Board of Supervisors over the summer. "I don't know what the controversy is."

Case dismissal: State regulators said they will dismiss a case against one of San Francisco's most popular all-ages music clubs after a judge ruled in favor of the Great American Music Hall this week.

The Great American Music Hall, a 38-year-old venue in the city's Tenderloin neighborhood, has been fighting the state Alcoholic Beverage Control for more than a year. The ABC claimed that the club had changed its operation to something different than what it represented in its license application. The basic issue is that the clubs are able to operate as all-ages venues because they sell food, but the ABC accused the business of operating as a nightclub. Similar cases are also pending against Slim's and Bottom of the Hill.

A hearing judge decided last month that while the rules are confusing, the club didn't violate ABC rules.

An ABC spokesman said in a statement that while the agency disagrees with the ruling, it has decided to dismiss the case and will work to clarify the rules.

Attorney John Hinman, one of the lawyers representing the club, said that the ruling is encouraging but that all the other cases should also be dismissed.
